SPECIFICATION forming part o'f Letters Patent No. 441,420, datedNovember 25, 1890.

v Application filed July l, 1890. Serial No. 357,327. (No model.)

' To all whom it may concern:

Be it known that I, WALTER S. JONES, of Lynn, county of Essex, State ofMassachusetts, have invented an Improvementin Heel- Nailing Machines, oflwhich the following description, in connection with the accompanyingdrawings, is a specification, like letters on the drawings representinglike parts.

This invention relates to heel-nailing machines, and is herein shown asembodied in an attachment adapted to be employed on heel-nailingmachines of any usual or wellknown construction.

My invention has for its object to provide simple and etiicientmechanism whereby heels may be nailed to boots and shoes with greaterrapidity.

In accordance with my invention the top- Vlift plate located below thedriver-block provided with drivers is operatively connected, as will bedescribed, to a driver-plate located above the said driver-block, sothat when one plate, as the driver-plate, is moved into operativeposition above the driver-block the toplift plate is moved out ofposition below the said driver-block, and vice versa, the movevthi-sspecification.

Figure 1 is an end elevation of a sufficient portion of a heel-nailingmachine embodying 'my invention to enable it to be understood.

Fig. 2 is a plan view, on an enlarged scale, of the attachment, shownseparately with the top plate removed. Fig. 3 is an under side View ofthe attachment shown in Fig. 2; Fig. 4, an

'under side view-of the top plate, showing the driver-plate in its fulland dotted line positions; Fig. 5, a side elevation of the attachmentandthe top plate; Fig. 6, a longitudinal section on line oo zu, Fig. 2,the gear being shown in elevation and the top plate being in itselevated position; Fig. 7,a longitudinal section on the line oc Fig. 2,showing the top plate in its lowest position and the heel nailed to theouter sole. Fig. S, a longitudinal section on the line x oc, Fig. 2,showing the driverplate withdrawn into its dotted-line position, Fig. 4,and the top-lift plate in its forward po- 'sition ready to have the toplitt applied, the 5-5 rack-bar being in elevation; Fig. 9, a section onthe line or, Fig. 2, showing the top plate in its lowest position andthe top lift applied to the heel, the rack-bar being shown in elevation;Fig. 10, a transverse section on the 6o line x x', Fig. 2; Figli, atransverse section on the line oc oc, Fig. 2; and Fig. 12, a sectionaldetail showing the completed heel.

Referring to Fig.'1,'A represents the framework of a beding-machine,which may be of v any usual or well-known construction, it be-4 ingprovided, as herein shown, with the pivoted jack a, upon which is placedthe boot or shoe o to be heeled. f

The frame A has secured to it above the 7o jack a my improvedheel-nailing attachment, (shown best in Figs. 2 to 11, inclusive,) itconsisting, essentially, of a block a2, having eX- tended from one endarms da a4, provided with preferably dovetailed slots on their inner 7 5sides, in which are fitted raclcbars o a6, (see Figs. 2, 3, and 11,)which mesh with an intermediate gear o?, pivoted on a stud or bolt as,extended through a cross-bar o9, securedto the under side of the arms a3at neartheir 8o outer end.

The rack-bar a5 has operatively secured to it a driver-plate b,preferably made of sufficient size to cover the holes or openings eX-tended through the block a2, and into which 8'5 are placed the driversb', the said holes or openings being made at their upper end of largerdiameter to form a shoulder b2, against which strikes the enlarged headb3 of the said driver when the latter is forced down through 9o the holeor opening to drive the nails into the heel b4. I

The driver-plate is herein shown as secured to the rack-bar a5 by meansof a pin or stud b5, secured toits underside and extendedinto a socketor hole in an upright post b on an arm Uf, (see Fig. 2,) secured to orforming part of the rack-bar. The rack-bar d6 has secured to it, as byscrews c, the top-lift plate c', (see Fig. 3,) having secured to it atop-lift holder, roo shown as a plate c2, provided with diverging armsc3 to embrace the rounded portion of the top-lift c4. The top-liftholder c2 is fastened by a pin c12 to an adj usting-bar c5, preferablydovetailed in a slot c6 in the top-lift plate. (See dotted lines, Fig.3.) The bar c5 is adjusted in its slot oG by a set-screw e8. Thetop-lift plate o is also preferably provided with a bar of on its sideopposite to the holder c2, the said bar being secured, as herein shown,to a lug or ear 020 by a set-screw 021, the said bar constituting a gageagainst which bears the substantially straight edge or side of the toplift to obtain the desired pitch of the heel. The top-lift holder c2 isnormally pressed forward, as herein shown, by a spring 01, one end ofwhich acts against the pin cl2 and the other end of which is Wound aboutand fastened to a stud or post 013 on the toplift plate.

My impro-ved attachment has co-operating 4 with it a movable cover ortop plate d, normally held elevated from the block d2 by springs d',encircling guide rods or posts d2, one at each corner of the plate,which are eX- tended into suitable holes in the block a2 and its arms a3d4. The top plate d is herein shown as provided with a longitudinaldovetailed slot 040, (see Fig. 4,) in which is iitted the driver-plateb.

In operation the parts normally occupy the position shown in Figs. and6, the top plate d being elevated, the driver-plate b being in itsforward position,the drivers being elevated by the nails d5, and thetoplift plate being withdrawn from below the block a2, the rackbar d5being in its forward position and the rack-bar asin its backwardposition. With the parts in this position the top plate d is moved downin any suitable manner, as by a foottreadle, (not shown,) until thedriver-plate b is brought in contact with the upper surface of the blocka2, at which time the nails d5 have been driven through the heel andinto theouter sole d and clinched, as clearly shown in Fig. 7. Theoperator removes the pressure upon the top plate, and the latter isrestored to its normal or elevated position, as shown in Fig. 6, by thesprings d'. The operator then pushes upon the handle d?, secured asherein shown to the rackbar c, and rotates the gear to withdraw thedriver-plate from above the block 0.2 into its dotted-line position,Fig. 3, and full line position, Fig. 8. As the rackbar c is movedoutward to place the driver-plate in its inoperative position, therack-bar 0.6 is moved in the opposite direction, and the top-lift platec, to which the top lift d has been previously secured, is placed abovethe heel in position to be spanked thereon. The top plate el is againlowered and brought into the position shown in Fig. 9 in engagement withthe block d2, thus spanking or rmly securing the top lift on the heeland forming the completed heel. (Shown in Fig. 12.) As soon as the heelhas been nailed the pressure is removed and the top plate d restored toits normal position,

and thereafter the boot or shoe is removed from the jack and a new oneplaced thereon and as soon as it is in position the operator pulls uponthe handle to move the rack-bar d5 forward and bring the driver-plateinto its operative position. (Shown in Fig. 5.) It

` will thus be seen that heels may be nailed to boots and shoes withsubstantially great rapidity, thus increasing the output of the machine,besides eecting a very considerable saving in time and labor'.

I claim- 1. In a heel-nailing machine, the combina tion, with adriver-block, of a driverplate and a top-lift 'plate located at theopposite sides of the said block, and means, substan tially asdescribed, to connect and simultaneously move said plates in oppositedirections to place them alternately 'in operative position withrelation to the said block, substantially as described.

2. In a heel-nailing machine, the combination, with a driver-block, of adriver-plate and a top-lift plate located above and below said block,respectively, and means to alternately move the said plates inand out ofline with the top and bottom, respectively, of said block, and a movabletop` plate above, and in which said driver-plate is moved, and springsto normally move the top plate away from the driver-block, substantiallyas described.

3. In a heel-nailing machine, the combination, with a driver-block, of adriver-plate and a top-lift plate located above and below said block,respectively, rack-bars to which said plates are respectively connected,and a gear in mesh with said rack-bars to move them in oppositedirections simultaneously, substantially as described.

4. In a heel-nailing machine, the combina tion, with a driver-block, of.a driver-plate 1ocated above'said block, a rack-bar to which said plateis connected, a top-lift plate located below said driver-block andprovided with an adjustable top-lift holder, a rack-bar to which thesaid top-lift plate is secured, and a gear in mesh with said rack-bars,substantially as described.

5. In a licei-nailing machine, the co1nbination, with a driver-block, ofa driver-plate 1ocated above said block, a rack-bar to which said plateis connected, a top-lift plate 1ocated below said driver-block andprovided with an adjustable top-lift holder and with an adjustable gage,a rack-bar to which the said top-lift plate is secured, and a gear inmesh with said rack-bars, substantially as described. l

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
